The heat pump may be connected to an earthed 220/2/50Hz -380/3/50 Hz general-purpose power supply.
This section is indicative and must be verified and adapted according to the installation needs and conditions.
Supply cable sections will follow the international standards. Next table shows some values for cable length
shorter than 5 m.
The acceptable tolerance to voltage fluctuation is +/- 10% during operation.

The electrical installation should be done by qualified professionals, keeping in mind the following points:
Connect the equipment following the wiring diagram included in this manual.
Place a U-curve thermal-magnetic circuit breaker in the general power connection to protect the line in the case of
a short in the circuit.
Place a differential circuit breaker in the general power connection to protect the equipment from possible
grounding problems. The differential breaker should be minimum 30 mA.
Before installing the connections, be sure to disconnect the electricity so that the power supply is turned off.
Connect the power supply wires to the machine's input terminal.
Connect the grounding wire to its corresponding terminal.
Connect the debugger control connections in parallel with the debugger time connection.
